Title: Scissor-type lifting platform
Inventor: KREMER ERWIN ING
IPC: B66F11/04
Filed: 1983-04-27
Granted: 1984-08-23
Abstract: A known scissor-type lifting platform has at least four scissor mechanisms which are arranged one above the other and which each consist of two scissor-arm pairs arranged congruently to one another in the horizontal transverse direction and having one outer and one inner scissor arm each which are centrally connected to one another via a scissor joint. The respective outer and inner scissor arms lying one above the other are connected to one another in an articulated manner at their ends, and a bottom lifting mechanism is arranged between the bottom first scissor mechanism and the second scissor mechanism, on one side of the vertical plane passing through the scissor joints, and a top lifting mechanism is arranged between two further scissor mechanisms on the other side of this vertical plane in each case between two scissor joints, adjacent one above the other, in the vertical direction in such a way as to act on scissor arms lying one above the other. The top lifting mechanism is here to be arranged in such a way that, without design changes, the scissor frame can alternatively be constructed with four or five scissor mechanisms arranged one above the other. To this end, the top lifting mechanism is arranged between the third scissor mechanism and the fourth scissor mechanism.

Title: Reinforcing structure for concrete mast - has horizontal tubes with ends shaped as springs or clips, for connection to vertical tubes
Inventor: URLBERGER KARL
IPC: E04H12/22
Filed: 1983-06-06
Granted: 1984-09-20
Abstract: The reinforcing structure uses set of e.g. four tubes (31) to form a square or rectangular tower, stiffened on its four sides by horizontal tubes (35,36). Two tubes (35) for two opposite sides are connected immediately below two tubes (36) for the two remaining sides, so that both ends of all horizontal tubes can be used for connection to the vertical tubes. These ends can be leaf springs, which fit round the vertical tube for an angle greater than 180 deg. Alternatively, the ends can be formed from wire (40,50) bent into loops to fit round the tube, each loop having parallel horizontal arms (41,42) at top and bottom. These designs can also be used for square vertical elements. ADVANTAGES - The system simplifies both transport and assembly of the components.

Title: Process and apparatus for the casting of slugs of aluminium for extrusion
Inventor: SAMAROPOULOS FEDON
IPC: B22D15/04
Filed: 1984-02-09
Granted: 1985-07-25
Abstract: In the process, casting is from a stationary casting ladle directly into casting moulds moving relative to it and having essentially the shape of the slugs, the pouring of the melt into the casting moulds being controlled such that material poured first is already solidified in the region of the casting mould walls before the casting mould has been filled with melt. An apparatus for the casting of slugs of aluminium for extrusion is distinguished by a stationary casting ladle, through whose casting opening numerous casting moulds, arranged on a drivable endless device, can be filled, and by a stripper device by means of which the contents of the filled casting moulds can be "headed".

Title: Device for the edge-equidistant and surface-flush setting and attachment of a headlamp housing in a vehicle-body section of the same shape
Inventor: SCHMID DIETER DIPL-ING
IPC: F16B39/282
Filed: 1986-08-27
Granted: 1987-11-26
Abstract: The invention relates to a device for the edge-equidistant and surface-flush setting and attachment of a headlamp housing in a vehicle-body section of the same shape. For the headlamp attachment at the lower side there is provided a screw connection via at least one screw-down angle which allows adjustment in three directions in space. At the top side the headlamp housing is provided for each screwing point with a threaded stay bolt with which the housing is attached to a cross-member. Attached to the threaded stay bolt is a setting nut widened in a flange-like manner and on the top side bearing a cross-recess; there engages in the latter a hollow screwdriver in the manner of a cross-recess screwdriver, which projects through the widened screw-passage hole in the cross-member. The setting nut is screwed in until it touches the lower side of the cross-member. When this happens locking nuts and locking tongues on the setting nut and cross-member, respectively, engage in one another in a locking manner and prevent further screwing in and above all unscrewing of the setting nut. After the setting nut is set in such a manner which is peculiar to each vehicle, a counter nut can be screwed onto the top side and tightened. The device allows headlamps to be quickly set and attached without testing and without using adjustment pieces despite scatter in the vertical position of the attachment cross-member.

Patent DE-3721844-C1 (DE)
Inventor: MEHLAN BERND
IPC: G07F11/22
Filed: 1987-07-02
Granted: 1988-11-17
Abstract: In a delivery device for an automatic vending machine, an ejector 6 for a goods pack 4, 5 is movable by means of a motor (9) along a circular path K. The delivery device 1 comprises only a single switch 11, which is closed by the goods pack 4 that is lowest on each occasion. On ejection of the goods pack 4, the switch 11 opens before the goods pack falls out. A control circuit detects the current switched state of the switch 11. The control circuit does not switch the motor (9) off, after opening of the switch 11, until the elapse of a delay time. Within this delay time, the goods pack 4 falls out of the delivery device 1. At the end of the delay time, the ejector 6 is again in its basic position G. The delay time may be varied in accordance with the time taken between switching on the motor (9) and opening of the switch 11, and in accordance with an average of previous delay times. This ensures that the effects of temperature and of the reducing weight of the stack of goods packs 5 are compensated. Provision may be made to detect blockages and other faults. The switch 11 also indicates when the machine is empty. <IMAGE>
